v I To all whom it may concern.-

Be it known thatI, CHARLES DYE, semen of the Republicof France, and a resident of Paris, France, have inventeda new and useful Improvement in Apparatus for Manufactun ing Tubes from Gelatinous Substances, which is fully set forth in the following specification.

paratusfor manufacturing tubes-from gelati- This invention relates to an improved ap:

nous substances, and is illustrated, by way of I example, in the accompanying drawin'gs, in

which- Figure 1' shows the apparatus in elevation, and Fig; 2 in plan.

Fig.3 is'an enlarged transverse section of Fig. 1, and Figl i isa still larger'sectiou showing in detail one of the draw-nozzles.

The apparatus is chiefly constituted by a trough A, provided at B with a partition which does not reach the bottom of the trough, a free communicating space beingleft between said partition and the bottom of the trough.

In the trough A are arranged in rows or in any other suitable manner air-tight cylinders 0, adapted to receive in their interior a certain pressure. Each of these cylinders C is provided at the top with a filling-cock C and a pressure-gage C for indicating the pressure in the interior of the" cylinder.

On one'of the longitudinal sides of the apparatus, as at D, is arranged a conduit for Into each cylinder 0 is introduced the paste or gelatinous substance employed in the manufacture of the tubes. Into the trough 'A is then introduced hot water, which enters first into the compartment A, where it is subjected to the action of a' Worm or stirrer A", which equalizes its temperature. Then the .hot Water passes underneath the partitions B into the reservoir A, where it surrounds the cylinders C, and thus maintains the paste at the temperature required for the Work. The cocks d are then opened, so as to place each cylinder under the pressure of compressed air. This pressure forces out the paste in the shape of tubes through the drawair,projected through orifices made in'tubes G G Opposite or around the'draw-nozzles E.

The cold air thus projected upon the gelaticeives a jerky motion, which prevents the tubes from sticking toit-r The tubes finally 7 "pass at J under the apparatus, Where they :may" be handled for sheathing or'covering them in a suitable manner.

The required motion, both for the rotation .of the worm A and for the movement of the table H, is obtained by means of a transmisa sion-gearing acting on a pulley K, keyed to the" spindle k of the worm A". A pulley L, keyed to said spindle 70, transmits the motion to an auxiliary spindle L, carrying the cams I.

The draw-nozzles may be, of course, of any suitable shape and size, according to the kind of tubes to be manufactured. r

The draw-nozzles E each contain a central head E, fixed therein, and a mandrel E which extends through the mouth of the nozzle.

What I claim is-- 1. 'An apparatus for manufacturing tubes from gelatinous substances, which consists of a cylinder provided with a draw-nozzle, means for heating the cylinder for maintaining the nozzle's"E,.and these tubes aresubjected at r this point .tothe action of currents of cold gelatinous paste in the same at the proper fluidity, means for subjecting the cylinder to internal air-pressure, and means for subjecting the formed tubes to the action of air-currents, as they issue from the draw-nozzle, substantially as set forth.

h 2. An apparatus for manufacturing tubes from gelatinous substances, which consists of a series of cylinders provided each with a draw-nozzle, means for heating the cylinders, means for subjecting the cylinders to internal air-pressure, an inclined table provided with grooves and onto which the formed tubes pass, and means for subjecting the tubes to the action of air-currents before falling onto said table, substantially as set forth.

In testimony whereof I have; signed this specification in the presence of-two subscribing witnesses.
